WebSolar Magnetic Field Typical magnetic field strengths for various parts of the Sun Polar Field: 1 - 2 Gauss Sunspots: 3000 Gauss Prominences: 10 - 100 Gauss Chromospheric plages: 200 Gauss Bright chromospheric … The core of the Sun extends from the center to about 20–25% of the solar radius. It has a density of up to 150 g/cm (about 150 times the density of water) and a temperature of close to 15.7 million Kelvin (K). By contrast, the Sun's surface temperature is approximately 5800 K. Recent analysis of SOHO mission data favors a faster rotation rate in the core than in the radiative zone above. Throu…

WebApr 14, 2024 · Coronal loops are arches of plasma that arc out from the solar surface, the photosphere, aligned along the sun's magnetic-field lines. These coronal loops act as … WebThe solar corona, chromosphere, and photosphere are distended, rarified regions that blur into each other and have definite form only when seen at great distance, as from Earth. The average density of the Sun, about 1.4 g/cm 3, is only about a quarter of that of Earth. deutsches apothekenportal movicol

In the Sun's photosphere, the most ubiquitous phenomena are granules—convection cells of plasma each approximately 1,000 km (620 mi) in diameter with hot rising plasma in the center and cooler plasma falling in the spaces between them, flowing at velocities of 7 km/s (4.3 mi/s). Each granule has a lifespan of only about twenty minutes, resulting in a continually shifting "boiling" pattern. Grouping the typical granules are supergranules up to 30,000 km (19,000 mi) in diameter … WebThe photosphere is the portion of the Sun seen in ordinary light.Its image reveals two dominant features, a darkening toward the outermost regions, called limb darkening, and … WebThe analyzed data sample the solar atmosphere of the field gradient of about 300 G/logτ when consider- from the deep photosphere to the middle chromosphere. ing the photospheric heights logτ =-0.5, -1.5, while Joshi In order to infer the physical properties of the penumbral et al.
